Iridium‐ and Rhodium‐Catalyzed Dehydrogenative Silylations of C(sp 3 )H Bonds Adjacent to a Nitrogen Atom Using Hydrosilanes

Now that is just silylated : In the presence of iridium or rhodium catalysts, C(sp 3 )H bonds adjacent to a nitrogen atom were silylated by the aid of a pyridine‐directing group. In iridium catalysis, a hydrogen‐trapping reagent such as norbornene or tert ‐butylethylene, which is usually required in late transition‐metal‐catalyzed dehydrogenative coupling reactions, was not required. In rhodium catalysis, however, 1 equivalent of COD (1,5‐cyclooctadiene) was necessary to induce higher conversion.
